Tight security arrangements have been made for President APJ Abdul Kalam and Prime Minister Manmohan Singh's visit in Cuddalore from January 3-7 in connection with the 94th Indian Science Congress.
Prime Manmohan Singh will inaugurate the five-day Science Congress at the Annamalai University in Chidambaram near Cuddalore on January 3.
President Kalam will declare open a children's science exhibition on January 5.
T Balasubramaniam, Director, Marine Biology, Annamalai University, said the theme of the Congress would be Planet Earth.
Eminent Scientists who will take part in the Congress, include Nobel Laureates Hartmut Michel of Germany and Aaron Ciechanover of Israel.
Union Minister of State for Science and Technology Kapil Sibal, Chief Minister M Karunanidhi, Scientific Adviser to Prime Minister CNR Rao, Principal Scientific Adviser R Chidambaram and Aricultural Scientist MS Swaminathan would grace the occasion.
Police said about 3,000 personnel would be deployed at the helipad and Annamalai University campus. A bomb squad would check the university complex thoroughly and metal detectors would be put in place.
Police are not taking any chances as a retired IIT professor of Delhi was killed in a terrorist attack at the Indian Institute of Sciences, Bangalore, in Dec 2005.
The heightened security is also in view of the fact that about a lakh devotees would gather for the 'Aarudra Darshan' festival at the Lord Nataraja temple in Chidambaram on January 3.
